IMPROVEMENT IN TRUSSES.

To ALL WHoM Ir MAY coNcnRN:

Be it known that I, JOHN A. W. IUSTI, of Savannah, in the county of Chatham. and State of Georgia, have invented a new land improved Truss for Hernia;- and I do hereby declare that the following is a full,l clear, andexact description-thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing, ,forming part of this specification.

The drawing presents a perspectivek view of the truss of my invention, showing the peculiar curve and arches of the pad-plate and its attachments.

The distinguishing feature of thistruss consists in the peculiar conformation of the pad-plate, which is not a simple flat spring, but is curved and arched in such manner that the pads maybe fitted accurately against the person of the patient, securing ease and comfort in the movements of the body. The spring or pad-plate has three arches or curves inthe transverse direction of the body, as it lies directly across from the prominence of the pelvis on one side to the prominenceof the pelvis on the other side, with twists at each extremity, and three double bends in the antero-posterior direction of the body. These arches, bends, and Vtwists of the pad-plate are made in proportions and relations as follows: The middle arch between the pads is shorter and shallower than the two side arches outside of the pads, and measures seven-sixteenths of an inch from the centre of the crown to the base line, while the side arches measure iive-eighths of an inch. The base lineof the middle arch is a straight line drawn from .the point of contact or attachment of the two pads, and the base line of the outside'arches is a straightline drawn from the points of attachment of the pads to the'ends of the plate. The twist onl cach end ofthe outside arches measures three-quarters of an inch, and commences close to the point of attachment of the pads, and gives them a curve of a semi-spiral character.

The pad-plate A is a thin metal band, made either of silver or brass or any other elastic and non-corrosive metal, steel not being admissible on account of its liability to rust by the moisture of .the body. The pads a a are hard wood disks, with a plate on the sides next the plate to which they are attached, and are pivoted by setscrews, b through longitudinal slots in the plate A for shifting and self-adjustment.V The belt cc for fastening the truss to the body is an ordinary web orstrap, n which is placed a sliding buckle, d, for adapting it to the person, with plates, e e, on each end, fastened bykey-hole slots to the buttons ff on the ends of the pad-plate A. There is also a band, g, attached to the belt e c for passing between the legs, and keeping the truss in place laterally, which is fastened onthe button or boss h in the middle of the pad-plate.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

Constructing a hernia truss with an elastic metal plate, A, formed by bending in thre distinct arches, the

two outside arches being twisted and curved, proportioned and arranged with reference to the pads aa, substantialy as and for the purposes herein specified.
